o the rat As anzaid for cookingithe stove-.isie'quipped In openation, a stove constructed on the principles of "the present invention offers many advantag'es. First among these is theiability to 'fre'gulate the cooking temperature at the grate bytr'aisin'g'or lowering/the entire upper structure as desired; "Furthermore, the cooking temp'erature at the griddle can be regulated either simultaneously with that at the grate by raising or lowering the upper'structure, or independent- "desired. :1 When the griddle'fhas sufficiently cooled, it can be swung back over the fire. The "griddle'igcan. easily be removed for cleaning and storing when theistove is *notin use so as to protect itifrom the weather. r #Another advantage isthat the combined grate andi griddle constructionof the top of the stove allows difierent foods to be 1 simultaneously prepared by different 'methods of ,jcooking. The griddle may also beused as a hot or warm plate, depending :on :itsposition relativeto the fire, or when in its outer position-shown in Fig. 1, it may be used as a table upon W-hichfood and cooking utensils maybe placed. In'passing it 7 a should be observed-that the combination of grid- ,with a griddle-,ia which islrectangular in shape. 1

Although the stove'illustrated in the particular embodiment of the invention shown and de scribed herein is a very sturdy and durable afiair, it is to lie-noted that all its parts-have been -.designed in a manner such that-they maybe fabricated by casting methods and because of the few machining operations required thestove may be manufactured and sold at a very low price. a Whilea stove constructed almost exclusively 0f; cast parts ,is not ordinarily -ver y portable bocause of its weight, a certain amount of portability is obtainedwhen such type of stove is conv structedin accordance with the principles of thisinvention becausefof; the fact that the var- 44 is formedon the underside Qfth griddle -38 and; rests upon the upper. surface OftheTbra ket M gwhen the -griddles mounted in position.
